restrict the set of accepted digest algorithms

[HW42]

Hi,

is there an option to restrict the set of "accepted" (see below) set of
digest algorithms (after searching the man page I don't think so)?

The desired behavior would be that gnupg simply ignores signatures made
with a algorithm not in the given set.

For example I would like to restrict the set of "accepted" algorithms to
SHA2 for code verification in a package manager like apt.
